  • Patent number: 7465824
    Abstract: A process is disclosed for producing at least one high purity aromatic carboxylic acid by oxidizing an aromatic feedstock with oxygen in a reaction medium comprising the aromatic feedstock, a promoter, a heavy metal catalyst, and a solvent which comprises benzoic acid and water to produce a reactor effluent wherein substantially all of the aromatic carboxylic acid produced remains in solution; and then hydrogenating the reactor effluent in the presence of a catalyst and hydrogen. This process efficiently and effectively produces high purity aromatic carboxylic acids by utilizing a common solvent for both oxidation and purification and eliminating the need for intermediate process steps and equipment.

  • Patent number: 6485651
    Abstract: This invention is directed to methods for quickly inverting and dispersing a flocculant in an aqueous slurry to achieve settlement of solids and clarification of the slurry water. In particular, this invention relates to methods for quickly inverting a flocculant-containing emulsion in-line without significantly destabilizing the emulsion. The methods comprise dosing water with at least one water-in-oil emulsion containing at least one of a flocculent polymer and a hydrophilic surfactant and subjecting the water and emulsion to a high shear, turbulent reverse flow, such that the combination of the surfactant and shear synergistically inverts the emulsion, so the flocculant may be directly injected into the slurry. In an alternative embodiment, the emulsion is fed directly to the slurry to be treated and subjected to high shear, such that the emulsion inverts in situ, releasing the flocculant into the slurry for solids/liquid separation.
